5 raruraru e ōrite ana ki:
\frac { \frac { 3 } { 4 } \times 2.5 } { \frac { 1 } { 2 } }
Tohaina
Kua tāruatia ki te papatopenga
\frac{\frac{3}{4}\times \frac{5}{2}}{\frac{1}{2}}
Me tahuri ki tau ā-ira 2.5 ki te hautau \frac{25}{10}. Whakahekea te hautanga \frac{25}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{\frac{3\times 5}{4\times 2}}{\frac{1}{2}}
Me whakarea te \frac{3}{4} ki te \frac{5}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{\frac{15}{8}}{\frac{1}{2}}
Mahia ngā whakarea i roto i te hautanga \frac{3\times 5}{4\times 2}.
\frac{15}{8}\times 2
Whakawehe \frac{15}{8} ki te \frac{1}{2} mā te whakarea \frac{15}{8} ki te tau huripoki o \frac{1}{2}.
\frac{15\times 2}{8}
Tuhia te \frac{15}{8}\times 2 hei hautanga kotahi.
\frac{30}{8}
Whakareatia te 15 ki te 2, ka 30.
\frac{15}{4}
Whakahekea te hautanga \frac{30}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
